FACT: In all the studies done, this has never been proven. The chemical is lightly sprayed to kill mold, algae and bacteria. A second coach may be used to kill any remaining mold and algae. Any remaining chemical runs off the roof. To ensure that the chemical does not damage the roof whatsoever, Dan Ryan’s Pressure Cleaning also takes the time to hose off the roof with fresh water after spraying the chemical on the roof. This is just a extra step we take to provide the best service and quality job in Palm Beach County.
FACT: Although the chemicals used can in fact kill plans, Dan Ryan’s Pressure Cleaning works hard to ensure we won’t damage your vegetation. We guarantee that your plants, landscape and vegetation won’t be harmed during your roof cleaning. We tarp any plants in the drip line of your roof, and any plants we know do not handle the chemical well. Our chemical is heavily diluted with water, to reduce the possibility of damaging your plants. We also have an employee on the ground at all times to spray fresh water on all your plants. If a plant dies, we will replace it.
Our guarantee means you never have to worry about damage to the landscape surrounding your home.
FACT: Pressure washing a roof requires you to walk across the delicate tiles, and with constant pressure washing, your tiles will fade in color. Broken tiles can cause leaks and roof damage. Our chemical cleaning puts zero pressure on your roof, and your roof will stay cleaner longer.
